Application filed August 15, 1813. Serial No. 785,006.

Z 0 ad whom it may concern 4 Be it known thatA l', HAROLD B. ANDERSON, a citizenv of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a Certain new and useful improvement in Signaling Devices, of which the following is a full, clear and exact description, reference being had to the accompanying drawings.

This invention relates, generally, to improvements in signaling devices or alarms for .use on vehicles, and particularly to electrically actuated devices of this character -which are especially'adapted for usele'n automobiles for attachment to the radiators thereof. Its objects are to provide such aA signaling device which is extremely eiii cient; substantial of construction; neat 'and attractive in appearance; and one which' can be quickly and conveniently secured to various types of automobile radiators without injury thereto.

The high eiliciency of my improved signaling device results from the employment of a pair of hammers which are actuated by a common vibrating means, the two hammers striking alternately and thereby increasing the effective vibrations. l' employ a bell in my device which Ais of sufficient depth to contain the actuating mechanism and thus protect it, and l support this bell by a tubular bracket through which the electric wires pass, thus shielding the wires from the effects of the weather; and these features combine to render the device neat and attractive in appearance. Furthermore, the supporting plate of the bracket is slotted for the reception of bolts for se'- curing it to the radiator, and these slots, some of which are vertically and others of which are horizontally disposed, permit an adjustment of the bolts and thereby render the device applicable to ,practically all styles of radiators..

My invention may be defined, generally, as consisting of the combinations of elements set forth in the annexed claims (in its preferred embodiment) illustrated in the accompanying drawing forming a parthereof, wlierein- Figure 1 represents my improved signaling device applied to an automobile radiator of the .well known honeycomb type, the bell being shown in central, vertical section and the section through the radiator being offset from the plane of the Vformer section in order to show the supporting bracket partly in elevation; Fig. 2 is a sectional plan on the line l; and Fig. 3 is a section on the line 3-3 of Fig. l and looking in the direction indicated by the arrows.

Taking up a detailed description of my invention, l represents a radiator of an au tomobile, the one shown herein being of of Fi g.

thewell known honeycomb type, as previously mentioned. A. supporting bracket 2 1s secured to the radiator by bolts 3 which pass through slots 4 in the plate 5 of the bracket, each bolt passing through one of the tubes 6 whereof the radiator is coinposed.4 A pad`7 of yielding material (such leather) is interposed between the rear face of the plate 5 and the front of the "radiator, and washers 8 ofsimilar material are inserted between the nuts 9 and the back of the radiator. These yielding or shock absorbing devices relieve the radiator tubes 6 of undue shock or strain and thus protect the radiator against injury. The end of the bracket 2 opposite the plate 5 is provided with a head lOhavinga vertical, central aperture 11 and a hole 12 extends throughout the bracket from the inner .face

of the plate 5 to the aperture 11, the pur-l pose of which will hereinafter be explained. Adapted to rpass freely through the'aper-v ture 11 in the head 10 of the bracket 2 is,

the threaded end of a post 13. This post issupported by'a combination nut and lamp socket 14 which bears upon the upper surface of lthe head 10, and located upon the post 13 and firmly clamped between the underneath surface of .the head 10 and the nutv 15, which is also threaded upon the post, is the sleeve 16 of the bell 17. The sleeve 16 is cut away at one point to form a channel 18 which is `adapted to register with the outer end of the aforesaid hole 12 in the bracket.

The post 13l is preferably made Ofcomparatively soft iron and its lower end portion is of greater diameter than the upper threaded part, and this enlarged portion provides. a core 19 for an electromagnet coil 20, the extreme lower end of the core being reduced at 21 where it passes through a hole in the core plate 22 and is then riveted. to firmly secure the core plate to the core 19.

The difference in diameter of the `core 19 and the threaded portion iio of the post 13 common to this class of work.V The free end of the angle arm 24extends down along lside the coil 20 yof the electromagnet an y carries, at its lower end a screw 26. The

L-shaped armature 27,'o the eiectromagnet has its horizontal branchrpivoted 'upon a pin 28 which extends through the core 19 a slightl distance above the upper end of the coil 20, and'its other branch extends down between the side of the oil and the aforesaid arm 24 where its lower endl is adapted to be attracted bythe core plate 22. .A keeper 29which is secured to the core late by a screw 30 limitsthe movement o the amature 'in a direction away from the core late. Aspring 31 is carried by the vertical branch of the armature and its lower free end is adapted to engage the platinum or silver point 32 of the screw 26. f

The upper end of. a spring stem 33 is secured, preferably by 'a drive-iit, to the free end of the horizontal branch of the armature 27 and this'. stem 33 extends downwardly within a short distance ofthe lower edge of the bell and substantially parallel with the side thereof and carries at its lower end `a hammer 34. The angle between the inwardly directed upper-'end of the stem 33 and its main portion is such as will support the hammer 34 a slight distance from the surface of the bell when the lower end of y thearmature 27 is in contact with the core plate 22, in which position it is shown in the drawing. In connecting the hammer 34. to

the stem 33, the stem is driven through the bore in the hammer and riveted. at 35. A

rod 36 which is threaded into a boss 37 prol '.from said hammer in a substantially horizontal direction across the bell to within a short distance Ioi' its other side where the rod is provided with a head 39. An auxiliary hammer 40 which is preferably spheriy cal invshape and which is provided with an axial bore 41 (a portion whereof is of the diameter of the body portion of the rod, 36

and the .other part of slightly greater diam-- eter than the head of the rod) is placed upon the rod before the rod is secured to the hammer'34, anda collar 42 which is pinned to the rod and spaced from its head 39 a distance slightly greater than the .length ofthe smaller portion of the bore 41,

structurecomprising the armature and the hammers with their respective stems, upon the pivot pin 28 to separate the lower end of the armature from the core plate 22. When the magnet. is denergized andthe s ring 43 permitted to act according to the a ve, the lower end of the armature. 27 will be swung away from the core and. against the outer endof the keeper 29, when the head 39 of the rod 36 will be projected toward the side of the bell 17 a'suiiicient distance to cause the hammer 40 to touch said bell, assuming, of course, that the auxiliary [shown at 47. The opposite end 'of the coil is connected by a wire- 48 to a binding post 49 which is located on an extension to the core plate 22. Any suitable means may be provided for supplying electric current to Ithe wires 414-45, and the circuit-may include any form of switch, preferably a push button which may be located in easy reach of the driver, as for instance, upon the lsteering wheel. When lthe circuit is closed by such device, current wiii be introduced into the electromagnet from the wire'44 to the angle arm24, and from here it will flow through the screw 26, the spring 31 to the I armature 27, through the pin 28, the core 19, core plate 22, binding post 49, wire 48, to the coil '20 of the clectromagnet, returning throughthe wire 4F to the source ofpower. The electromagnet, being thus energized, will attractthe armature 27, causing it to rock upon its pivot pin 28 and swing the hammer 34 against the side ofthe bell.-

Thc resiliency of the stem 33 is suiiicient to cause the ham'rner to bridge the gap which normally exists between such hammer and the adjacent surface of the bell; and because v ot its quick recoil, thehammcr 34 will oder no interference with its clear vibrations.'

ion

Immediately upon the swinging of the armature 27 against the core plate 22, the conn -nection is broken betweenthe screw 26 and the spring31 thereby breaking the circuit and denergizing the magneti Upon the magnet being so denergized, the spring43 retracts the hammer 34 and causes it, through the rod 36, to project the auxiliary hammer 40 with considerable .Torce against the opposite side of the bell. TheJrecoil resulting from the impact of the auxiliary hammer against the bell causes such ham--` mer to slide backwardly upon the vrod ipto engagement with the collar 42, and being removed from the zone of vibration ofthe Limena bell, the hammer in no way interferes with' the clear sounding thereof. Under the conditions which permit the spring to actuate the hammers, the armature 27 is back against the keeper 29, and in such position throws the lower end of the spring 3l against the screw :2G and restores the circuit to cause the repetition of the foregoing operation. v

To piiotect the wires-Ll--l from the w eather sleeve 16 of the bell 17 to the interior of the bell; and at this same point 1 lead oli' al pair of branch wires 44a-45 from the respective wires '44 and 45, and these have connection .with thesocket which forms a part of the nut 14. Supported 1oy theA socket is an electric lampl() .(which is preferably red as such color is the conventional indication of danger). In this manner l place in multiple with the sounding alarm, an electric lighting signal which is illuminated simultaneously with the sounding of the alarm.

From the foregoing description it will be seen that I have provided a signaling device for automobiles which is very compact and which, while involving an electrically actuated vibrating means of ordinary principle, has its etliciency materially increased by a novel construction of hammer, and the method of conducting the-wires through the hollow supporting bracket of the bell is also an important feature of my invention.

The manner in which 1 sec-ure the supporting bracket to the radiator whereby the radiator is relieved of shock or strain and the adaptability of the bracket to various` types .of radiators through the adjustment provided by the slots 4 in the plate 5, are

i also points of importance. f
